Bipin Ravi b01140256b fix(cpus): workaround for Neoverse V2 erratum 2719105
Neoverse V2 erratum 2719105 is a Cat B erratum that applies to all
revisions <= r0p1 and is fixed in r0p2.

The erratum is avoided by setting CPUACTLR2_EL1[0] to 1 to force
PLDW/PFRM ST to behave like PLD/PRFM LD and not cause invalidations
to other PE caches. There might be a small performance degradation
to this workaround for certain workloads that share data.
